Question
What happens to your weight when you are in a lift which
goes down?Solution
The weight decreases when the lift moves down and it increases when the lift moves up. As the lift moves down, we observe a pseudo force which acts on the opposite direction of the weight of the body. Hence, the net weight decreases. As the lift moved up, we observe a pseudo force which acts on same direction as that of the weight of the body. Hence, the net weight increases. Hence, option A is correct.
